Application filed December 15, 1913.

To all whom it may concern:

Be it known that 1, JOHN 1V. RANSOMER, a citizen of the United States,residing at Batesville, in the county of Independence, State ofArkansas, have invented certain new and useful Improvements inIntermittent Operating Mechanism; and I do hereby declare the followingto be a full, clear, and exact description of ,the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to transmission gearing for motor vehicles andtractors.

The object of the invention resides in the provision of a transmissiongearing which will eliminate the use of spur gears more or lesscomplicated compensating mechanism.

A'further object of the invention resides in the provision'of atransmission gearing of the character referred to which will be simplein construction, efficient in use, and which may be manufactured andinstalled at a comparatively small cost;

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the sev eral views, and in Which Figure 1 is aplan view of the improved transmission gearing applied to a tractor;Fig. 2, a side elevation of Fig. 1 with the near rear wheel cut awayfor. the purpose of disclosing the part connected to the extension onthe inner end of its hub; Fig. 3, a section on the line 3-3 of Fig. 2;Fig. l, a view of a fragment of what is shown in Fig. 2 with the partsset to effect a backward movement of the tractor; Fig. 5, an enlargedsection on the line 55 of Fig. 1; Fig. 6, a perspective view of one ofthe oscillating arms of the structure and certain conti uous partscoiiperating therewith.

Referring to the drawings A indicates the frame of a tractor, B thefront axle, and O the rear axle. Mounted upon the front axle B are theusual traction wheels 10, while traction wheels 11 are mounted upon therear axle C for rotation thereon. Each of the traction wheels 11 hassecured to its Specification of Letters Patent.

inner side a hub extension 12 for a purpose that will presently appear.Rotatably mounted upon the frame A between the axles B and C is atransverse shaft 13 which has fixed thereto adjacent one side of theframe A an operating lever 14 through the instrumentality of which theshaft 13 may be rotated. This lever 14 carries a spring pawl 15cooperating with a toothed segment 16 mounted upon the frame A for thepur pose of securing the lever 14 in a desired adjustment. Also fixedupon the shaft 13 in the same plane with the lever 14 and adjacent theopposite side of the frame A is an arm 17. Rotatably mounted on theframe A between the rear axle C and the shaft 13 is atransverse shaft 18which is adapted to be rotated through the medium of suitableconnections with the motor of the tractor (not shown). The shaft 18 isprovided adjacent one end with crank portions 19 disposed oppositely andin the same plane- This shaft 19 is also provided adiacent its other endwith crank portions 20 disposed onpositely to each other and in a planeat right angles to the crank portions 19.

Rotatably mounted on each hub extension 12 are rings or yokes 21 and 22each of which has formed integral therewith a forwardly extending arm 23provided adjacent its free end with a longitudinal slot 24:. lhe inneredge of each ring 21 and 22 is recessed as at 25, said recess beingdisposed in line with the arm 23 and having its rear wall converg- 1ngfrom its center in each direction toward the periphery of the hubextension 12. Pivotally mounted on each arm 23 is a forked angle lever26 which carries between its arms for limited bodily movement relativeto the arm a roller 27 extending through the recess 25 of the collar 21or 22 with which said angle lever is associated. It will be noted thatthe axis of rotation of the roller 27 is parallel to the axis rotationof the axle C and that by oscillating the angle levers 26 the rollers 27can be moved from one end of the recess 25 to the other. Secured tocrank portions 19 and 20 are corresponding ends of links 28, the otherends of said links being slidably engaged in respective slots 24: of thearms 23 whereby rotation of the crank shaft 18 will effect anoscillation of the arms 23 and the rings 21 and 22.

A rod 29 has one end connected with the lever 14: and is slidablyengaged through a bar 30. The end of the rod 29 remote from the lever'14 has engaged thereon a head 31, while another head 32 is mounted onsaid rod between the lever ll and the bar 30. Encircling the rod 29 andhaving one end bearing against the head 31 and its other end against thebar 30 is a spring 33. Also encircling the rod 29 and having one endbearing against the head 32 and its otherend against the bar 30 is aspring 34:. The terminals of the bar 30 are connected respectively toadjacent angle levers '26 by means of rods 35. A similar structureconnects the arm 17- with the angle levers 26 which are associated withthe rings 21 and 22 mounted on the extended hub 12 of the wheel 11 whichis located on the opposite side of the tractor and the same referencecharacters are employed to designate such similar parts.

In the operation of the transmission it will be obvious that when thelever 14 is disposed in the position shown in Fig. 2 the rollers 27 willall be disposed at the upper ends of respective recesses 25 and inbinding relation to both the periphery of the adjacent hub extension 12and the rear wall of the adjacent recess 25 so that when the arms 23 aremoved downwardly theaxle G will be locked to the corresponding ring 21and 22 with the result that the rotation of the shaft 7 18 will effect arotation of the axle C in a direction to move the tractor forward. \Vhenthe lever 14: is disposed in the position shown in- Fig. 4 the rollers27 will be positioned at the lower ends of respective recesses 25 sothat the collars 21 and 22 will be locked to Copies of the axle C onlywhen the arms 23 move upwardly. With this status present it will beobvious that the rotation of the shaft 18will eifect a rotation of theaxle C in a direction to cause backward movement of the tractor. lVhenthe lever lei is disposed vertically or at right angles to the frame Ait will be apparent that the oscillation of the rings 21 and 22 will bewithout efiect on the'axle C.

lVhat is claimed is The combination with a motor vehicle frame and adrive axle rotatably mounted on the frame, a ring rotatably mounted onthe axle, an arm on said ring, the ring be ing provided with a recess inits inner walls adjacent the axle, said recess tapering from its centertoward each end, a drive shaft mounted on the frame, and including acrank portion, connections between the crank portion and the arm wherebythe protation of the shaft will oscillate the ring, a bell-crank pivotedon the arm, a roller carried by-the bell-crank and engaged in the recessof the ring, and adapted to connect the ring and axle during movementofthe ring in one direction, a lever pivoted on the frame, and a yieldingconnection between the lever and bell-crank.

In testimony whereof, I a'tlix my signature, in the presence of twowitnesses.
